The 25-year-old striker has been linked with a move to Leeds United in the summer transfer window.
Kalmar sporting director Andersson-Borstam has suggested that the club are open to selling the striker this summer.
Andersson-Borstam, though, has made it clear that the move has to suit both the club and the player.
"It is clear that his performances have not gone unnoticed,” Andersson-Borstam told Swedish outlet Fotbollskanalen, as translated by The Daily Star. "He is at the top of the top scorers and is perhaps the league's best player right now.
"We are very happy if a player is performing so well that he can go on to bigger clubs. But it must match from every perspective. It has to be right for both Antonsson and Kalmar FF."
FotbollDirekt.se reported earlier this month that Aston Villa and Cardiff City were also interested in signing Antonsson in the summer transfer window (click here to read more). However, it now seems that the striker is on his way to West Yorkshire outfit Leeds.
Andersson-Borstam’s comments about Antonsson being the best player in the Swedish top flight (Allsvenskan) should be encouraging for Leeds fans.
The Whites do need a good striker in order to complement or act as back-up to Chris Wood. It remains to be seen how Antonsson adapts to the Championship, but Leeds fans should be optimistic.
